The announcement came even as its two main markets, Britain and South Africa, are reeling under subdued consumer demand due to lower spending and local restrictions.
Group turnover for the three months ended Dec. 26 rose to 12.2 billion rand from 11.6 billion rand, the company said.
Its shares rose after the announcement and were up almost 10% at 1330 GMT.
TFG, formally known as The Foschini Group, said online group turnover rose 32.3% for the quarter ended Dec. 26, with a 114.1% jump in TFG Africa. Group online sales contributed 12% to nine-month-ended Dec. 26 overall group sales.
TFG Africa, it's biggest unit which houses Jet stores, grew turnover by 14.7%, boosted by its clothing and homeware divisions.
Sales in TFG Australia, its third operating region, were up 0.4% in Australian dollars, supported by minimal lockdown restrictions in November and at the start of December, which resulted in a strong sales trend into Christmas, TFG said.
In London, sales performance continues to be negatively impacted by a government-enforced national lockdown and reduced levels of consumer demand for occasion and formal workwear. Sales plunged 41.4% in British pounds.
It said it does not expect a near-term recovery in sales in Britain amid the latest lockdown.
Excluding the Jet acquisition, which added 1.2 billion rand ($80.42 million) to group turnover, group third-quarter sales fell by 4.8% to 11.1 billion rand.
TFG bought Jet in September from struggling department chain owner Edcon after it filed for business rescue earlier this year.
On Tuesday it said it had received further approvals to buy the rest of Jet's operations in Botswana, the Kingdom of Eswatini (formerly Swaziland), Lesotho and Namibia.
